摘要： A bias signal is applied to a resistive thermal sensor located proximate a magnetic media reading surface of a magnetic sensor. The bias signal is modulated between first and second bias levels. First and second resistances of the resistive thermal sensor corresponding to the first and second bias levels are measured. Based a difference between the first and second resistances caused by in increase in thermal conductivity between the magnetic sensor and a medium as the magnetic head gets closer to the medium, at least one of a spacing and a contact between the magnetic sensor and the medium are determined.

摘要： A slider includes a leading edge, a trailing edge, a transducer adjacent to the trailing edge, and an air bearing surface. The air bearing surface includes a forward pad, a rearward pad, and a center rail pad feature disposed along a longitudinal axis of the slider. The center rail pad feature includes a first shallow recess finger and a second shallow recess finger diverging from the longitudinal axis toward the trailing edge.
